Increases in housing stock in Sydney and Perth have failed to match population growth in these capitals, according to research from the Australian Housing and Urban Research Institute (AHURI) and the Bankwest Curtin Economics Centre (BCEC).

The report, titled Housing Supply Responsiveness in Australia: Distribution, Drivers and Institutional Settings, takes a look at how well supply is keeping up with demand across Australia’s regions and capital cities. 

Lead researcher and deputy director of BCEC, Professor Rachel Ong, said while national growth in Australia’s housing stock has kept pace with population growth over the last ten years, the picture is very different for some of our major capitals. 

“Increases in Perth and Sydney’s housing stock over the past ten years have been insufficient to match the increase in their growing populations, with supply-side barriers more acute in Sydney than Perth,” Professor Ong said. 

The issue of housing affordability is more nuanced than previously thought, with most new housing concentrated in mid-to-high price market segments, it says.

“We’d normally expect to see a trickle-down effect, where building higher-value homes leads to the opening up of lower-value homes for those on lower incomes. Our research indicates this isn’t the case, meaning an increase in housing supply is not leading to better housing affordability,” Professor Ong said.

In its executive summary, the research said that a one percent increase in the level of real housing prices is estimated to produce a 4.7 percent (3.9 percent) increase in new house (unit) supply. These house price gains translate into a very small increase in the housing stock which will do little to keep up with demand pressures.  

 

“This indicates that a broader policy response is needed to address the structural impediments that weaken the 'trickle down' impact on new housing supply. There is a real need for targeted government intervention, including measures that improve financial incentives for developers to build at the lower end of the housing market.”

A positive finding from the report is that the supply of units is more likely to be concentrated in job-rich areas, with more than 50 percent of new units built in the highest job density areas in Australia. 

 

“A likely result of that will be shorter commuting time to work, which offers an important boost to productivity,” Professor Ong said.
